'HHHHEHHHH] II S March 1931- G. L. HARPHAM OIL DISPLAY DEVICE Filed March 1, 1930 2 Sheets-Sheet 2 dtmmu Fatented Mar. 17, 1931 UNITED STATES GEORGE L. HARPHAM, OF CORONA, CALIFORNIA OIL-DISPLAY DEVICE Application filed March 1,

This invention relates to a device, for display and demonstrating purposes.

An object of this invention is to provide an improved device for demonstrating the quality or clearness of a liquid such as oil.

A further object is to provide a novel advertising device adapted to attract the atten tion of onlookers.

Still another object is to provide an automatic display device which is simple in construction.

Other and incidental objects, advantages and features of the invention will readily appear from the following description of an embodiment thereof taken in connection with the accompanying drawings.

In the drawings, Fig. 1 is a view in front elevation of a display device embodying the present invention.

Fig. 2 is a rear view of the mechanism of the device.

Figs. 3 and 4 are enlarged detail views of the lost-motion connection in the shoulders of the figure forming a part of the device.

Fig. 5 is a side view of the mechanism shown in Figs. 1 and 2.

Fig. 6 is a sectional View of the pivotal connection between the spouts of the receptacles shown in Fig. 1.

Fig. 7 is an enlarged side View of one of the receptacles in Fig. 1, and

Fig. 8 is a modification of the lost-motion connection in the shoulder of the figure as shown in Figs. 2, 3 and 4.

Referring to the drawings, and particularly to Figure 1, the figure illustrated, which is mounted on a base 10, is provided with out wardly extending arms 18 and 19 carrying a pair of receptacles 11 and 12. The receptacles 11 and 12 are provided with spouts 13 and 14; secured to them at points 15 and 16 for pivotal movement. These spouts are also joined to each other (see Fig. 6) by a pivot pin 17 so that there may be relative movement between them around the pin 17 as an axis. The arrangement of these spouts and their connections with each other and with their respective receptacles is such that the contents of the receptacle which is raised will be directed into the other receptacle.

Means to be described later are provided for raising and lowering first one of the arms 18 and 19 and then the other and so on for an indefinite period. It will be understood that as this movement continues the contents of the receptacles will be poured back and forth in uninterrupted operation and that the various qualities of the contents, for example oil, as they pour through open space will be demonstrated to an observer.

' The mechanism controlling the movements of the arms 18 and 19 comprises a rod; or member 20 extending through each arm and pivotally mounted on a support 21 secured to the base 10. A pin 22 is provided on each receptacle which extends through and is secured to the rod 20 in anyknown and desired manner. 8

A link 23 depends from each of rods 20 and has a slot 24 running lengthwise thereof. A walking beam 25 is fastened on a supporting member 26 for oscillation about a pivot 27 Pins28 secured to the beam 25 project into the respective slots 24 in links 23. A rotary wheel 29, wrist pin 30, and connecting rod 31 transmit the driving power of a motor 32 to the beam 25.

A head piece 33 is mounted on the member 26 so as to impart a lateral tilting movement to the head of the figure as it is rocked about a pivot 34; by means of the crossed connecting links 35 attached to the walking beam 25.

Having described the mechanism shown in the drawings to illustrate the invention, I will now explain its operation. When the display device is in its normal position, that is, with both receptacles in their lowered position, pins 28 rest in the lower portion of their respective slots 24:, as shown in Fig. 2. On the tip-stroke of the connecting rod 31, the left side of the walking beam 25 will rise, the respective pin 28 moving towards the other end of its slot without effecting movement of link 23. In the meantime the right side of beam 25 is moving down carrying its respective link 23 with it by virtue of the engagement between the right-hand pin 28 and the bottom of its respective slot. As the right-hand link'23 moves down, themember 20 on the right will'raise the right arm 18 to a position Where the contents of the raised receptacle 11 will flow into the other recepits movement, the right side rising and permitting the right arm and its rod 20 to be lowered to the normal position by the weight of the receptacle it carries.

As the rod 31 enters the third quarter of its movement, the right side of beam 25 will continue to rise and carry the right pin 28 up through slot 24 without efi ecting any move ment of its respective link 23 and member 20, while" the left side of beam 25 with its pin 28 moves the left link 23, member 20, and arm 19 in a manner similar to the movement on the right side of the figure in the first quarter of'the movement of rod 31, and pours the contents of the receptacle 12 back into the receptacle 11 as indicated in Fig. 1.

As the rod 31 approaches its initial position (going through the fourth quarter) the left arm and its mechanism return by gravity action as did the right arm in the second quarter.

. The above-mentioned slot and pin connection between the beam 25 and the arms may be referred to as a lost-motion connection. This connection, as is evident, allows for a complete up and down movement of each arm and the receptacle it carries before the other arm and receptacle are moved.

As the arms of the figure go through the above movements, the head of the figure is tilted toward the side on which the receiving receptacle. is. located. This tilting which is first to one side and then to the other is kept instep with the movements of the arms by the connecting links 85.

I It is also to be understood that the arms of the automaton may carry objects other than receptacles, and that the automaton may be used without receptacles or the like in which case the head and arm movements of the automaton will attract the attention of passers- Fig; 8 shows a modification of my lostmotion connection in which a strap 36 is secured to each end of the walking beam 25 in lieu of links 23. The straps 36 are intended to engage bars 37 projecting inwardly from the rear ends of rods 20 and secured to the latter in any known and desired manner. The operation of this modified structure needs no explanation as it is substantially like the previously described lost-motion connection.

Apparatus of preferred form and con structi-on has been illustrated and described for the purpose of showing a way in which this invention may be practiced, but the inventive thoughtupon which the invention is based is broader than this illustrative embodiment thereof and no limitations in the scope of the invention are intended other than those imposed by the appended claims.
